REFLECTOR-SHADE.

Specification of Letters Patent.

Patented Oct. 2, 1906.

Application filed May 2, 1905. Serial No. 25 8,463.

To all whom, it inay' concern.-

Be it known that I, WILLIAM H. SPENCER, a citizen of the United States,residing at Brooklyn, in the county of Kings and State of New York, haveinvented certain new and useful Improvements in Reflector-Shades; and Ido hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same, reference being hadto the accompanying drawings, and to numerals of reference markedthereon, which form a part of this specification.

The present invention has reference generally to improvements in thatclass of reflectors for incandescent electric lights, which reflectorsare rovided with a centrally-disposed screw-t eaded collar forattachment of the shade of the reflector upon a screwthreaded fixture orbracket.

This invention has for its principal objects to provide a simple andcheaply-constructed reflector of the general character hereinafter setforth and, furthermore, to provide in connection with the shade of therefiectora novel and simple clamping or holding means for securing thescrew-threaded collar which is to be screwed upon the fixture or bracketto or within a centrally-disposed opening in the shade of the reflector,the said clamping or holding means of the screw-threaded collar being ofsuch a construction that the parts are intimately and securely unitedand cannot become disconnected or loosened when screwing thescrew-collar upon the fiX- A further object of this invention is toprovide a novel and positive means for immovably securing one or morescrew-receiving sockets or devices to the shade to receive the screws bymeans of which the usual lightcluster is secured upon inner centralortion of the shade of the-reflector; and, fina ly, another object ofthis invention is to cover and entirely surround the marginalreinforcing bead or turnover of the reflector-shade with a layer ofenamel or other suitable material, so as to provide the reflector-shadewith a straight u per face at all points and prevent all possibi ity ofwater during rain and snow storms from lodging upon the shade to thedetriment of the enamel and the shade proper.

My present invention consists, therefore, in the novel reflector-shadehereinafter set forth; and, furthermore, this invention consists in thevarious arrangements and combinations of the several devices and parts,as well as in the details of the construction of the same, all of whichwill be more fully described in the following specification and thenfinally embodied in the clauses of the claim which are appended to andwhich form an essential part of this specification.

The invention is clearly illustrated in the accompanying drawings, inwhich Figures 1 and 2 are a top and bottom view, respectively, of areflector-shade embodying the several improvements of my presentinvention; and Fig. 3 isa longitudinal vertical section, on an enlargedscale, said section being taken on line 3 3 in said Fig. l of thedrawings. Fig. 4 is a sectional representa tion of a portion of thereflector-shade, showing an arrangement of o enings or holes for thecentral fiXture-attac 'ng ring and a pair of cluster screw-receivingsockets, the said ring and screw-receiving sockets also being shown invertical section, but in their detached relation with thereflector-shade and about to be inserted in their assembled posi tionsin the respective holes or openings in the reflector-shade. Fig. 5 is asimilar sectional representation of the parts represented in said Fig.4, but showing the fixture-ring and the cluster screw-receiving socketsin theinimmovably-fixed positions relative to the shade of thereflector. Fig. 6 is a detail vertical section of the marginal andbeaded edge of the shade and the layers of porcelain or other similarmaterial upon the upper and inner faces of the shade and about the beadto provide the shade upon its upper face with a straight andunobstructed surface for the water to run off from the said shade. Fig.7 is a side view of a modified fixture-receiving ring; and Fig. 8 is ahorizontal section ofthe same, said section being taken on line 8 8 insaid Fig. 7 looking in the direction of the arrow :70 in said Fig. 7

The reflector-shade herein described is character were also providedwith a central fixture-receiving ring and with cluster screwplane of theupper face of the shade, the

parts of course being enameled, as usual; but

when thus made the shade always had a marginal portion raised above theplane of the u per 'face of the shade, and the result was t at thewater-from rain and snow invariably lodged against the raised part orshoulder. This had a deteriorating efl ect in that the water, due to.the elements and changes in the weather, caused the enamel in time topeel away, whereby the metal body of the shell becamerusted and wasrendered unsi htly. Furthermore, in time the refle'c-.

torade thereby was rendered useless and had to be replaced.Reflector-shades of this receiving sockets; but the method and means-e'mployed for securing the said ring and screw-receivin sockets to thecomparatively thin metal bo y of the shade was such. that an ineflicientand insecul'e'fastening. means was the result, and. especially with thefixture-receiving ring in screwing thesame too forcibly-upon the screwportion of the fixture or bracket, the soldered or otherwise-fastenedring'was easily dislod ed from its operative position upon the sha e orwhen not entirely dislodged was sufiiciently loosened to render; thedevice inoperative.

Referrin now to the several figures of the 1 drawings, t e referencecharacter -1 indicates or body of the same.

the reflector-shade, and 2'is the metal shell portion the said shell orbody is made with a receiving-opening 3 for the reception of. afixture-receiving ring 4. The said shell or body 2 may also "be-providedwith two or more other openings 5 for the rece tion ofclusterscrew-receiying sockets 6. he said fixture-receiving ring 4 isprovided with an internal screw-thread .7 and usually with av tighteningor binding set-screw 8. The saidfixture-receivmg ring is also madewith/a downwardly-extendin annular. flange 9, the lower marglnal edge 0which is made thin or is chamfered upon its 'inner surface, as at 10 andas clearly shownin Fig. 4 of the draw-- ings. The u per outer surface ofthe said sockets 6 when employed are each provide with aninternally-screwthreaded receiving portion 14 for the rece tion of thescrewthreaded portions of t e usual screws by means of which thelamp-cluster is secured in its position u on the inner face of the reflector-shade. ach clustenscrew-receiving socket 6 is also made with adownwardly-e15- tending annular flange 15', the lower marg1- Inits uppercentral into the upward] ly as shown at-13. In a nal edge of which ismade thin or is chain fered upon its'inner surface, as at 16. The

upper outer surface of the flange 1-5 and the lower portion of the mainbody of eachsocket 6 are made insuchf a manner that an annular shoulder17 isformed, the lower surface of each shoulder 17 referably taperinwardly and inward y in the manner s own at 18 in Fig.4 of' thedrawings.-

' Referrin now to Fi s. ings, it wil be seen .t atwhen the annular,flange 9 of the fixture-receiving ring' 4 is inserted in the centralreceivmg-opemng 3 in the shell or body 2 of'the reflector-shade itsundercut shoulder 11 will rest directly u on the upper surface portionsof the said s ell or body 2' which'bound the said opening 3. In likemanner when the vcluster screw-receiving sockets 6 are inserted in theres cctive openings 5 in the said shell or b0 y 2 each undercut shoulder17 will rest directly upon the u per surface portions of the said shellor bo y 2 which boundthe said openings 5. After the said r 4 and sockets6 have thus been arrange the chamfered marginal flanges 9 and 15 of thering 4 and sockets .6, respectively, are u set a amst the 4and 5 of thedraw under surface portions of t e sai shell or body 2in the mannerillustrated in Fig. 5 of 1 the drawin s. From an inspection of said Fig.5 it mi 1 be seen that the upsetting and closing down of the saidflanges9 and v 1.5 against theunder-or inner surfaceportions' o the shellor-body 2 which bound lJhBVEL-P rious openings 3 and 5 draws the saidbound- IOO' ing portions of the shell or body 2 upwardly I parts of the'shoul ers 1'1 and17 offthe ring 4 and inwardly .tapering and sockets 6,respectively. In this manner .the said ring 4 and sockets 6 are securelyfastened to the metal body or shell of the reflector-shadeagains'tdisplacement, as will be clearly evident. Furthermore, thismeans and method of connecting the rin 4 and sockets 6 to'the shell orbody2 provi' es water-tight connections at these points, as

will be clearly seen from an ins cation of Figs. 3 and 5. 'Referrin nowto. 3-and '6 of the drawings, it wi 1 be seen t at said shell or body 2is made'with an annular and downwardly-curved portion 19 and with aturned-over edge portion 20, terminating in Thisv edge 21 is praceanannular edge 21. tically in the same plane of the main shell or body 2,the annular head which is formed by these parts being slightly below theplane of the main shell or be y 2.

A coating or layer 23 of porcelain, enamel, or the like of one color,usually green, is placed upon the: upper and outer face of the shell orbody 2,'-sa1 '12 5 layer preferably e'xtend- 1 .ing around the marginalhead of the said f shell or 'body 2 and sli htly upon the inner-marginal edge portion 0 the-shell or body, as

at 24,- the remaining surface of the inner face 1 0 seaeso oi the saidshell or body 2 being provided with layer 25 of white enamel or othersimilar material. In this manner the upper layer 23 provides a perfectlysmooth and unobstructed surface for any water to run off therefrom, anda reflector-shade which is perfectly waterproof is the result.

1 am aware that some changes may be made in the arrangements andcombinations of the parts, as well as in the details of the constructionof the same, without departing i from the scope of this invention. HenceI do not limit my invention to the exact arrangements and combinationsof the parts as described in the foregoing specification and asillustrated in the accompanying drawings, nor do I confine myself to theexact details of the construction of the said parts.

Having thus described my invention, what I claim is 1. In areflector-shade, a metal shell or body formed with an opening bounded byan upwardly-extending marginal edge, and a receiving-fixture in saidopening, said fixture having an internally-screw-threaded receivingportion and bein provided with an annularly-extending groovecorresponding to and in which said upwardly-extending marginal edge isarranged, said fixture being pro-- vided below said groove with anoutwardlyu or other layer upon the upper surface of said shell andaround the said upwardly-bent marginal edge, the upper and outer face ofthe said layer being perfectly straight to prevent a collection of waterupon the shade, substantially as and for the purposes set forth.

In testimony that I claim the invention set forth above I have hereuntoset my hand this 26th day of April, 1905.
